If you use a fixed grid, maybe with square cells, then you have to add a transition callback and modify the texture x,y,width and height of the snap artwork. You can use this trick to "crop" the original image so that only the square center area is used. If you have thumbs with incorrect aspect ratio (pixel perfect thumbs) you can use the same tick to correct the aspect ratio to 3:4 or 4:3.

Sorry, my coding skill doesn't good enough. Could you make a sample (nut file) to me based on your theme? Many Thanks.

I think "irregular" grid is difficult to do. So, I will pass it and using fixed grid. But one thing would like to do.For AM default coding, it can be only handle fixed size of box art image. If you see Parallelism web layout, it can handle different size of image very well whether is vertical image or horizontal. Do you have any idea?

Do you know how to let first box display "game system"? like as above ideal mod "MAME" text box? Also, how to display game name in each box? Agree with one row is easy, but do you know how to make 2 rows?

Anyway, thank you first, I will try to make a mod up base on your theme later

Tried updating to 1.13 but there's a problem when you move the cursor left or right out of the screen the cursor disappears. Any ideas?

This is not a bug or something wrong. This is a effect only. I would like to make screen clean while fast jump to next game

Are you sure? Because how it's happening for me is, for example, I move the cursor all the way to the right past the last icon. Then the whole icon list shifts and recenters and the cursor disappears all simultaneously. But if I move the cursor back to the left and scroll through the games, there is still no cursor. I can keep pressing left or right and scroll through the games and the name of the game is shown on the bottom bar (changing with every press) but without that you would never know what game your currently hovering over.
